When comparing our production JDeveloper/ADF 10.1.3.2 against Visual Studio 2005's ASP .NET technology, one of the few areas where Microsoft has a functional edge is in the area of "Master Pages" or page templates. Similar to the "slide master" of a Powerpoint presentation, the master page contains all of the common "chrome" that every page in the application should share, along with content zones that individual "slides" fill in with slide-specific content.
After watching Frank Nimphius' screencast about the new feature on the OTN 11g Tech Preview demos page, Andrejus Baranovski blog's about our new page template capability in JDeveloper/ADF 11g that gives us now a first-class templating solution for JSF applications, along with the ability to easily work with template-based pages in the visual editor. The page template can contain both static or ADF data-bound content, as well as any number of replaceable content zones that pages based on the template will fill-in with page-specific content.
Give it a try with the JDeveloper/ADF 11g Technology Preview and give us some feedback in the Oracle JDeveloper and OC4J 11g Technology Preview OTN Discussion forum.
